Description

This update for ghostscript fixes several issues. These security issues were fixed :

  • CVE-2017-9835: The gs_alloc_ref_array function allowed remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted PostScript document (bsc#1050879).

  • CVE-2017-9216: Prevent NULL pointer dereference in the jbig2_huffman_get function in jbig2_huffman.c which allowed for DoS (bsc#1040643).

  • CVE-2016-10317: The fill_threshhold_buffer function in base/gxht_thresh.c allowed remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted PostScript document (bsc#1032230).

  • CVE-2017-9612: The Ins_IP function in base/ttinterp.c allowed remote attackers to cause a denial of service (use-after-free and application crash) or possibly have unspecified other impact via a crafted document (bsc#1050891).

  • CVE-2017-9726: The Ins_MDRP function in base/ttinterp.c allowed remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted document (bsc#1050889).

  • CVE-2017-9727: The gx_ttfReader__Read function in base/gxttfb.c allowed remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted document (bsc#1050888).

  • CVE-2017-9739: The Ins_JMPR function in base/ttinterp.c allowed remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted document (bsc#1050887).

  • CVE-2017-11714: psi/ztoken.c mishandled references to the scanner state structure, which allowed remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PostScript document, related to an out-of-bounds read in the igc_reloc_struct_ptr function in psi/igc.c (bsc#1051184).

  • CVE-2016-10219: The intersect function in base/gxfill.c allowed remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted file (bsc#1032138).
